T at whom it may concern.-

Be it known that I, CHARLES OWENS. a citizen of the United States,residing at Chattanooga, Hamilton county, Tennessee, have inventedcertain n'ew and useful Improvements in Pamphlet-Ooverers, of which thefollowing is a specification. 7

My invention relates to machines for applying covers to magazines,almanacs, and the like; and it consists in the features and combinations and arrangement of parts hereinafter described, andparticularly pointed out in the claims. Y

In the accompanying drawings, Figure 1 is a side view of the invention.Fig. 2 is a plan view of the same.

In the drawings, 1 indicates a table upon which rest the covers whichare to be applied to the magazines or almanacs. This table is movablevertically by means of vertical screw-shafts 3, operating through nuts 2on the edges of the table. The movement of the' table is step byv stepand is adapted to keep the upper surface of the pile of covers in thesame central horizontal plane, so that the upper sheet will always hearthe same relation to the feeding mechanism. This step-by-step movementof the table is effected from an ec-; centric-shaft 4, supported in'theframework at 5 and having an eccentric 6 operating a rod 7, carrying aspring-pawl 8 to engage a ratchet-Wheel 9 on one of the screw-shafts.The screw-shafts are connected together by a transverse shaftl0,extending above the table and journaled in suitable hearings in theframework, said shaft having beveled gears 11 thereon meshing withsimilar gears on the screw-shafts.

The mechanism for feeding the covers comprises a suction or pneumatictube 12, pivoted at or near its upper end at 13 to a housing or standard1a and connected by a pipe 15 with a fan-casing 16, containing asuitable form of fan for exhausting theair from the pneumatic feeder.The lower end of this pneumatic feeder is normally slightly above theupper surface of the pile of covers on the table 1. It has oscillatingmovement imparted to it by means of an eccentric and strap 50 17. Thesuction through this tube will cause the upper cover-sheet to be raisedfrom the paste-applying pads 25.

pile, and then the tube swinging toward the left will thrust the end ofthe cover-sheet between feed-rollers 1819, which are constantlyrotating, and by these the sheet will be fed onto a traveling belt 20,which directs it to feed-rollers 21, the action of which will behereinafter described.

On the shaft 10 Irarrange a paste-applying device,-which also serves thepurpose of buc- 6o kling up the top one ofthe covers and assists inproperly feeding the covers one at a time to the'transmitti-ng-rolls 1819. This paste- 25'is made to contact with a paste carrier or roller 26,which rotates in atrough 27, and at the next step the pad, which hasjustreceived a supply of paste, will contact with the uppermost cover of thepile and apply theretoa 8o streak of paste, said streak extendingtransversely of the cover-sheet and being approximately of the samewidth as the thickness of the magazine to which it is to be applied.

At the next step movement of the paste-applying device the topmost coverof the pile will be buckled up, as shown in dotted lines in Fig. 1, sothata proper separation will take place between this topmost sheet orcover and theothers of the pile by reason of the admission of air to thespace between said topmost sheet and the balance of the pile. By thismeans accuracy of feed is insured, as the action described will preventthe feeding of two sheets at a time. The step-by-step 5 movement of thepasting and sheet-buckling device is given by means of an eccentric-rod28, operated from an eccentric on the shaft 4, before described, saidrod having a pawl 29 to engage a ratchet-wheel 30 on a sleeve I00 31,surrounding the shaft 10 and connected with the drum 22. The cover orsheet having been pasted and fed between the rollers 21, beforementioned, is moved by said roller forwardly with its forward edgedirected up the inclined plane 32, supported by the framework 33 inanysuitable manner and having atits upper end a stop or abutment 34,against which the edge of the cover-sheet may strike. The parts are soproportioned in relation to the length of the cover that when theforward edge of the cover strikes the stop or abutment 34 the centralpaste-covered portion of the sheet or cover lies substantially betweenthe feed-rollers 21 and directly in the path along which the magazine isfed.

Themagazines are piled in a hopper 35 adjacent to the feed-rollers 21,and they are fed one by one by means of oscillating fingers 36, onearranged at each forward corner of the hopper and adapted to engage thelowermost magazine of the pile and move the same into the bite of therollers 21 and into contact with the cover-sheet at the point where thestreak of paste has been applied to said sheet. These feed-arms arecarried by upright shafts 37, suitably journaled in the frame, having attheir lower ends beveled gears 38, meshing with similar gears 39 on across-shaft 40, to which an oscillating movementis imparted by an arm41, attached thereto, operated by an eccentric-rod 42 from a suitableeccentric on the shaft 4, before described. These feedarms 36 simplyintroduce the magazine to the bite of the rollers 21. It will be ofcourse understood thatfrom the moment the magazine begins to passbetween the rollers 21 and contacts with the cover there will be nofurther feeding action of the rollers on the cover itself tending toforce it up the incline, and the portion of the cover lying on theincline 34 will remain at rest, while the other portion in the bite ofthe rollers will feed forward with the magazine. The moment the magazinecontacts with the inclined coversheet its tendency is to bend itintermediate of its length rather than to force it up the incline 34,this being due to the fact that the movement of the magazine is acrossthe incline plane of the cover-sheet. The course of the magazine isthrough the passage 43 over a suitable table 44. This course, as will beseen from Fig. 1, is at an angle to the inclined position of thecover-sheet, and as'the magazine moves horizontally along'the pathway 43the cover-sheet will be carried along with the magazine, and it will befolded upon the same to form the front and back flaps of the cover, andits paste-covered central portion will be pressed upon theback edge ofthe magazine to adhere thereto. For this purpose an abutment 45 isarranged to extend across the pathway 43 and at right angles to the saidpathway. The cover as it enters the pathway 43 and is bent over theedges of the magazine will engage with the face-of this abutment andwill be pressed squarely against the back edge of the magazine to afforda firm and even contact of the cover throughout said edge. As themagazine moves onward this abutment will yield, for which purpose it ispivotally supported at 46 and is held upright by a spring 47.

Returning to the action of the feed-rolls, it

will be seen from Fig.2 that the roll 18 and also the uppermost roll 21are formed with only their end portions of a sulficient diameter, as at48, to afford feeding contact with the cover-sheets. In other words, thecentral portions of these rollers are cut away about their shafts. Bythis construction the rollers will feed the sheets without contact withthe paste-covered portions thereof, as it will be At 49 I show anautomatic gate which is pivoted at 50 and is held normally in a positionindicated in Fig. 1 bya spring 51. This gate serves to direct the frontedge of the cover-paper as it emerges from the rollers 21 onto theinclined plate 32 and to prevent this front edge of the paper from beingcaught and passing into the horizontal pathway 43. When the magazine isfed along the pathway 43, together with the cover-sheet applied thereto,this gateway will yield and offer no obstruction. After passing throughthe way 43 the magazine, with its applied cover, is discharged, by meansof rollers 52, onto a series of parallel bars 53, forming a gratingsupported by a frame 54. In the case of almanacs, which after receivingtheir covers are to be stitched, I provide means whereby the saidalmanacs may be opened and placed one upon the other, so thatthey may beconveniently fed to the stitching-machine. For this purpose I provide anendless belt 54', running transversely to the direction in which thealmanacs are discharged. The almanacs when discharged strike a stop orabutment 55, and they lie upon the grating 53. The belt 54 has pushersor arms 55 thereon to extend up between the bars of the grating, andthey engage the bottom edges of the magazine and push the samelongitudinally along the grating, so that a pointed bar 56 will enterbetween the leaves of the almanac close to the back thereof. Thecontinuous movement of the pushing-arms will free the almanac from thesupport aii'orded by the grating, and the said almanac will then turn bygravity, with its back edge uppermost, and will be then supported by thepointed bar. When the next almanac is thrust upon the pointed bar, theone just placed thereon will be moved forward along the said bar andover an enlargement 57 of said bar having inclined surfaces 58 forgradually opening the almanac. In this way the almanacs may be properlyopened to be placed one on the top of the other in order that they maybe readily fed to the stitching-machine.

The difierent parts of the machine may be driven in any suitable way.

The suction of the pneumatic feed-tube is intermittent, and for thispurpose I provide an automatically-operating valve at 59, consisting ofa slide movable through the pneumatic feed-tube and having an opening tobe moved into and out of line with the passage through the feeding-tube.This slidewhen the feeding-tube swings forwardly strikes an abutment orstop 60, supported on'the frame, and is thereby thrust backwardly, thusbringing the imperforate part of the slide in line with passage throughthe feeder to cut off the suction. This cutting off takes place when thecover-sheet enters between the feed-rollers 18 19, and thus the sheet isreleased at the proper moment. As the feed-tube swings back over thepile of sheets and gets in position to take the next top sheet theslide-valve strikes another abutment 61, and this shifts the valve intoposition with its opening in line with the suction-passage, and thesuction at once lifts the uppermost sheet to be attached thereto for thefeeding operation, and as soon as the sheet has been taken by the feederthe paster operates to buckle up the sheet to separate it from the restof the pile. The paster-pad being moist adheres sufficiently to thepaper to insure its proper buckling and separation. 1

The machine is driven from a belt-wheel 62 on the shaft of the lowerroller 21, which has a gear 63 meshing with a large gear 64, journaledon a stud on the frame. Thislarge gear meshes with a gear 65 on theshaft of the lower feed roller 18, and this is sufficiently broad tomesh with a gear 66 on the roller 19 and alsoa large gear-wheel 67 onthe eccentric-carrying shaft 4:. The rolls 52 are driven through gearing68 69 from the gear 63. The belt 54 is driven in any suitable'manner.

By reason of employing an oscillating feedarm the said arm retractsafter it has fed the magazine to the bite of the rolls, and in thisretracting movement it holds up the pile of the magazines, holding thesame separated from the magazine being fed and preventing more than onemagazine being fed at a time.
